Regimen Transition After Short-Term Intensive Insulin Therapy in Type 2 Diabetes

Starting soon · Phase 4

Conditions studied: Type 2 Diabetes

In brief

Failure of oral antidiabetic drugs (OADs) is a frequent challenge in patients with type 2 diabetes mellitus (T2DM), and inadequate long-term glycemic control substantially increases the risk of diabetic complications. Short-term intensive insulin therapy (SIIT) is an established approach to mitigate glucotoxicity; however, the optimal strategy to sustain long-term glycemic benefits after SIIT in T2DM patients with OAD failure remains unclear. To address this gap, we designed a randomized controlled trial to evaluate subsequent treatment options, aiming to identify a simple and effective regimen for patients with poor glycemic control who undergo SIIT. A total of 324 eligible patients will be enrolled. After screening, previous antidiabetic regimens will be discontinued, and patients will be randomly assigned to the SIIT- iGlarLixi group (A), the SIIT-IDegAsp group (B), or the SIIT-iGlar group (C). All patients will be hospitalized for short-term insulin pump therapy, followed by 24 weeks of treatment: group A with insulin glargine/lixisenatide, group B with insulin degludec/aspart, and group C with insulin glargine U300 plus metformin. During the extension follow-up period, patients in all groups may either continue their assigned regimen or return to their original pre-study therapy. A total of 10 clinic visits are scheduled for each patient throughout the study. Primary endpoint is proportion of patients achieving glycosylated hemoglobin A1C \<7% at 24 weeks.Secondary endpoints include proportion of patients achieving glycosylated hemoglobin A1C \<6.5% at 24 weeks; differences in weight gain, hypoglycemic events among treatment groups, and differences in proportion of patients continuing the assigned regimen, glycemic control and body weight at the extension follow-up period.

You may qualify if…

• Diagnosed with type 2 diabetes mellitus (T2DM) with a disease duration of >1 year and <15 years.
• On a stable dose of at least one oral antidiabetic drug (OAD) for ≥3 months.
• HbA1c at screening: >8.0% if on a single OAD; >7.5% if on more than one OAD (centralized laboratory testing, or results from medical centers participating in the National Glycohemoglobin Standardization Program).

• Able and willing to comply with study requirements, including continuous glucose monitoring, self-monitoring of blood glucose, lifestyle management, and insulin-based glycemic management.
• Agreement to use effective contraception during the study.
• Willingness to provide written informed consent.

You may not qualify if…

• Diagnosis of type 1 diabetes mellitus or other specific types of diabetes.
• Receipt within 3 months prior to screening of premixed insulin therapy and/or basal-bolus insulin therapy and/or basal insulin plus OAD therapy for ≥7 cumulative days; or receipt within 1 year prior to screening of intensive insulin therapy (insulin pump or multiple daily injections); or receipt within 3 months prior to screening of GLP-1 receptor agonists; or inability to tolerate protocol-specified doses.
• Known hypersensitivity or intolerance to study medications.
• Acute diabetic complications (including diabetic ketoacidosis, hyperosmolar hyperglycemic state, or lactic acidosis).
• Severe microvascular complications: proliferative diabetic retinopathy; albumin excretion rate (AER) >300 mg/g or proteinuria >0.5 g/day; uncontrolled painful diabetic neuropathy or significant autonomic neuropathy. Severe macrovascular complications: hospitalization for acute cerebrovascular accident, acute coronary syndrome, peripheral artery disease requiring intervention or amputation within the previous 12 months; unstable angina, myocardial infarction, uncontrolled arrhythmia, or severe heart failure (New York Heart Association [NYHA] class ≥III).
